Background/aim: Enlarged polypoid gallbladder lesions should first be evaluated to rule out gallbladder cancer. Gallbladder lymphoma rarely develops, and gallbladder follicular lymphoma is seldom observed.

Case Report: The case of a 70-year-old man with an enlarged polypoid gallbladder lesion and stable-sized multiple enlarged mesenteric lymph nodes is reported.

Background: Follow-up is recommended for an asymptomatic unilocular hepatic cystic lesion without wall-thickness and nodular components. A few liver cystic lesions represent biliary cystic neoplasms, which are difficult to differentiate from simple cysts with benign mural nodules on imaging alone.

Case Presentation: An 84-year-old woman with a history of simple liver cyst diagnosed one year prior was admitted for evaluation of a developed mural nodule in the cystic lesion.

Article Synopsis
  • Hepatic artery pseudoaneurysms are rare, occurring in about 1% of cases after metal stenting for malignant biliary issues, with fewer instances following plastic stenting for benign conditions.
  • A case is presented involving a 61-year-old man who developed hemobilia following the placement of plastic biliary stents, despite lacking common risk factors.
  • Successful treatment of the pseudoaneurysm was achieved through superselective transarterial embolization, and monitoring with imaging techniques is advised if hemobilia occurs post-stenting.

It has been reported that patients with macroscopic vascular invasion accompanying hepatocellular carcinoma have a poor prognosis. Modern molecular therapy with multitargeted tyrosine kinase inhibitors and immune checkpoint inhibitors has shown promising results in patients with metastatic hepatocellular carcinoma; however, molecular therapy is limited to patients with Child-Pugh class A disease. This review summarizes the present status of surgical therapies, including conversion hepatectomy, for patients with MVI in the developing era of novel molecular therapy.

Article Synopsis
  • Patients with bilateral lung metastases from hepatocellular carcinoma (HCC) typically receive molecular therapy, with atezolizumab and bevacizumab showing potential for long-term survival.
  • A 67-year-old woman treated for HCC experienced metastases in her lungs and underwent multiple therapies, including lenvatinib, atezolizumab plus bevacizumab, and later cabozantinib and dual immune checkpoint inhibitors.
  • Despite limited response from some treatments, she maintained stable disease for extended periods while preserving liver function and quality of life.

Article Synopsis
  • Hepatocellular carcinoma (HCC) associated with bile duct tumor thrombus (BDTT) is aggressive, requiring ongoing, multidisciplinary treatment approaches for effective management.
  • The study presented two cases of elderly men with advanced HCC and BDTT, who underwent complex surgical and interventional therapies, including extended liver surgeries and transarterial chemoembolization (TACE).
  • Both patients achieved complete remission without viable tumors and maintained good health nearly two years post-treatment, highlighting the effectiveness of the Vater papilla-preserving strategy for long-term survival in such cases.

Background: Fluorouracil plus leucovorin (5-FU/LV) is a less toxic but mild chemotherapy.

Case Report: A 63-year-old male patient with rectal cancer and multiple colorectal liver metastases (CRLM, total volume of 1,826 ml) was hospitalized. He had several poor prognostic factors, including elevated levels of tumor markers, with carcinoembryonic antigen and carbohydrate antigen 19-9 levels of 17,119 ng/ml and 7,617 U/ml, respectively.

Background: Large numbers of synchronous colorectal liver metastases are associated with poor prognosis.

Case Report: A 47-year-old male patient with rectal cancer and unresectable colorectal liver metastases (over 15 cm in diameter and over 30 metastases) was treated with a multidisciplinary treatment including systemic chemotherapy with mFOLFOX6/panitumumab and surgical therapies (colostomy, modified associating liver partition and portal vein ligation for staged hepatectomy together with radiofrequency ablation). For solitary recurrent colorectal liver metastases, percutaneous radiofrequency ablation with chemoembolization and open radiofrequency ablation in combination with the same systemic chemotherapy was performed.

Background: Colorectal cancer is the third most commonly diagnosed cancer in both men and women, and one of the more widely recognized preventable cancers. Adenosquamous carcinoma (ASC) of the colon/rectum is an uncommon disease that consists of both glandular and squamous components, and the most common site of ACS is the right and transverse colon.

Case Report: Here, we present the case of a 78-year-old woman, who complained of abdominal pain.

Background: Bile duct adenomas (BDA) may be precursor lesions of small duct-type, including mass-forming type intrahepatic cholangiocarcinoma (ICC).

Case Report: A 68-year-old woman was transferred to our facility for the treatment of a liver tumor, possibly metastasized from a pancreatic neuroendocrine tumor. Finally, two liver tumors were resected and histopathologically diagnosed as "BDA" and "ICC with a BDA-like component".

Background: The liver is the digestive organ where metastatic adenocarcinoma of unknown primary site is most often observed.

Case Report: A 74-year-old man was diagnosed with a growing gallbladder tumor and multiple liver tumors limited to the left lateral sector. Liver tumors were suggested to be primary or secondary adenocarcinoma with no relation to the gallbladder tumor.

Background: Hepatic inflammatory pseudotumor (HIPT) is an uncommon benign tumor-like mass that mimics malignant tumors.

Background/aim: The prognosis of cholangiolocarcinoma, a rare malignant liver tumor derived from hepatic progenitor or stem cells, is considered relatively good; however, it frequently recurs. We herein present the diagnosis, histological findings, and treatment of cholangiolocarcinoma.

Case Report: A 65-year-old woman with a large liver tumor (70 mm in diameter) was referred.

Multidisciplinary treatment is recommended for the management of patients with advanced hepatocellular carcinoma (HCC). Some operative decollateralization of extrahepatic feeding arteries with laparotomy have been introduced for HCC. We herein newly develop laparoscopic devascularization (LDEV) to continue transarterial chemoembolization (TACE) for HCC with extrahepatic collateral arteries.

Aim: To assess the utility of the perioperative use of direct oral anticoagulants for patients with hepatocellular carcinoma (HCC) with cancer-associated thrombosis.

Case Report: An 83-year-old woman was admitted with a solitary HCC (10-cm diameter), as well as with multiple sites of venous thromboembolism and macroscopic portal vein tumor thrombosis. She had appropriate liver function without viral hepatitis, triple-positive tumor markers, and secondary polycythemia.

Aim: Our aim was to confirm the utility of Indocyanine green (ICG) fluorescence imaging for intraoperative detection of adrenal hepatocellular carcinoma (HCC) metastasis.

Case Report: An 83-year-old man with a right adrenal HCC metastasis was admitted after complete remission of primary HCC and a metachronous left adrenal metastasis. He was treated with ICG fluorescence-guided limited resection to preserve adrenal function.

Hepatic sclerosed hemangioma is a rare benign liver tumor that originated from hepatic cavernous hemangioma; however, the process of its formation has been unclear. We herein present the patient of a histologically proven hepatic sclerosed hemangioma that showed drastic changes in diagnostic images in a short period. A 56-year-old man was referred to our hospital for the treatment of suspicious hepatocellular carcinoma with hepatitis C, approximately 2 cm in diameter in liver segment 8.

A simple and sensitive method for the determination of 8-hydroxy-2'-deoxyguanosine (8-OHdG), a marker of oxidative DNA damage in human urine, was developed using automated on-line in-tube solid-phase microextraction (SPME) coupled with stable isotope-dilution liquid chromatography-tandem mass spectrometry (LC-MS/MS). Creatinine was also analyzed simultaneously to normalize urine volume by the in-tube SPME LC-MS/MS method, and 8-OHdG and creatinine were separated within 3 min using a Zorbax Eclipse XDB-C8 column. Electrospray MS/MS for these compounds was performed on an API 4000 triple quadruple mass spectrometer in the positive ion mode by multiple reaction monitoring.
